MILK-CAN.

fiIECIFIGATION forming part of Letters Patent No. 684,923, dated October22, 1901.

' Application filed March 13, 1900. Serial No. 8,613. (No model.)

To aZZ whom it may concern:

Beitknown thatLBENJAMIN DRAPER, a sub ject OfJJhB Queen of England, anda resident of Liverpool, England, have invented certain new and usefulImprovements in Milk-Cans, of which the following is a specification.

This invention has reference to cans or ves sels used for thetransmission or for holding and transmission of milk and cream, and hasfor its object, primarily, to provide improvements in connection withsuch cans or vessels by which milk shall be capable of being transmittedover lengthy journeys and also kept a long time without affectingmaterially itsquality or condition or at any rate which will enable itto be carried or transmitted so that its quality or condition shall bebetter than that which exists in the case of milk as at present carriedand contained.

In a milk-can according to the present invention the cover is in theform of a valve and the parts are so constructed that all the air isdisplaced from above the milk in the closing of the can after it hasbeen filled.

Theinvention will now be described with the aid of the accompanyingdrawin gs, in Which- Figure 1 is a sectional elevation of a milkcanaccording to this invention. Fig. 2 is a plan of same, and Fig. 3 is adetail of the neck of the can. Fig. 4 illustrates in side elevation amodification of the invention, and Fig. 5 is a plan view thereof.

Referring generally to the drawings, a, is the body of the milk-can, ande is the cover. In the neck of the body a there is a metal ring 12,having an inclined inwardly-projecting seat I), on which an inclinedface e of the cover e rests when it is placed in the can, and this coveris held in place by a bridge-bar c and screw-spindle d, as hereinafterdescribed, the bridge-bare being detachably held by the sides of thering I) by providing it with the angular recess 11 which extends fromits up per edge downward and then at right angles, as shown clearly inFig. 3. At the center of the cover e there is an aperture it, withinwhich fits a valve f, which when in place is pressed down into positiononto its seat in h in the cover by the spindle d.

In use when the can is nearly full the cover 6 is placed in position inthe ring I), resting on the seat I), and then some milk is pouredthrough the central valve-aperture h until it stands near the level ofthe upper part or neck of this aperture, the effect of which is that allthe air is displaced from the can, and it is entirely filled with milkwith no vacant space at all in it. Then the valve f is placed in theaperture h and is pressed down onto its seat by a screw d, (the bridge 0of which has been inserted in its holding-recesses 72 and thus both thevalve f is pressed upon its seat and the cover e upon its seat b andtight joints are made and the can is closed. The cover e is provided onits edge with a projecting part c and below with a projecting ledge 6 bywhich the face 6' is protected from damage when the cover is ofi, andthe under surface of the cover is conical or concave, as shown, toassist in the expulsion of the air through the central valve-aperture hwhen the filling and closing take place.

The parts of the apparatus shown and set forth with reference to Figs. 1to 3 are made of metal of any suitable kind.

A modified form of cover is shown in Fig. 4. It has a coned lowerportion e below the face e, and with this construction if the can befilled with milk nearly up to the seat I) when the cover I] is placed inposition the air is displaced and also a small quantity of milk, so thatno space within the can exists for the milk to move about. The cover 6in this case is, in effect, a valve, and it may be of any suitablematerial, such as wood or light metal or other suitable material.

What is claimed in respect of the hereindescribed invention is In a milkor like can, the combination of the body a, and internal ring I), havingan internal valve-seat b, a cover 6 having a face e on its periphery, anopening it in the cover, a valve f opening outward and fitting on a seatin the opening it, and a screwdown-spindle d, supported by a detachablebridge 0, detachably held at its ends by the ring I); substantially asset forth.

In witness whereof Ihave hereunto set my hand in presence of twowitnesses.
